Process of manufacturing ornaments

ABSTRACT

An ornament is manufactured with the aid of an element composed of horizontal wires which form a stone mount, and vertical wires which cross and are joined to the horizontal wires to form upstanding tips and depending legs. The element is placed onto a die with the legs extending upwardly, a base thermally bonded to the legs, and a stone is engaged with and fixed by the tips.

SHEET 2 BF 2 PROCESS OF MANUFACTURING ORNAMENTS This invention relates to an ornamental element for use in the manufacture of ornaments and to a process of manufacturing ornaments.

It is known to manufacture ornaments in an economic manner by machines and by casting. These processes enable a manufacture of series of identical ornaments but do not enable a manufacture of different individual ornaments.

This disadvantage is eliminated by the present invention. The ornamental element provided according to the invention for use in the manufacture of ornaments is characterized by the provision of crossing wires, including vertical wires to be joined to a base on one side and to fix a stone on the other side, and transverse wires adapted to be interconnected to form a stone mount. The stone mounts composed of transverse wires are provided with upstanding tips of wire for holding a stone and depending legs of wire to be joined to the base. The use of this element enables a combination of individual ornaments of prefabricated ornamental elements.

The process of manufacturing such ornaments is characterized in that the stone mounts are placed on a die so that the legs of wire are on top, and these legs are then jointly soldered or welded to the base consisting, e.g., of an annular rail. For this purpose, the stone mounts provided with the legs of wire are embedded on the die in the proper position in magnetizable metal powder and are thus held in the position in which they are to be soldered or welded to the base.

Various embodiments of ornamental elements according to the invention are shown by way of example in the drawing,

which includes also a sectional view illustrating the process of manufacture according to the invention.

FIGS. 1 to 8 are, respectively, side elevations and top plan views of ornamental elements according to the invention in the form of stone mounts.

FIGS. 9 and 10 are, respectively, a sectional view and a top plan view showing an assembling device for use with the elements of FIGS. 1 to 8.

As is apparent from the drawing, the stone mounts 1 shown in FIGS. 1 to 8 consist of crossing wires. Vertical wire legs 2 are intended to be fixed in the base 3 in accordance with FIGS. 9 and 10 and the wire tips 4 serve to hold the stone, whereas the transverse pieces of wire 5 are interconnected to form a stone mount.

FIGS. 1 and 2 show, respectively, an oval mount and a rectangular mount. FIGS. 3 and 4 show, respectively, a trapezoidal mount and a drop-shaped mount. FIGS. 5 and 6 show, respectively, a circular mount and an oval mount, and FIGS. 7 and 8 show ornamental elements of fancy configuration for use in making ornaments.

FIGS. 9 and 10 illustrate the manufacture of ornaments, such as rings, in accordance with the process according to the invention. An assembling plate 7 is mounted on guide pins 8 in the apparatus 6. This assembling plate 7 consists of a metal electrotype, which has been strengthened with synthetic resin. The stone mounts l are then applied to the assembling plate 7. A holder for the base 3 consisting, e.g., of an annular rail, is also mounted on the guide pins and consists of a rail guide 9 having an extension 9a. When the stone mounts l are inserted, the legs 2 are bent so that a common soldered joint can be formed in the cap 10 of the annular rail 3. Before the soldering operation, the stone mounts l are embedded in magnetizable metal powder 11 on the assembling plate 7 and the electromagnetic plate 12 is energized to hold the mounts 1 in position.

The use of different assembling plates 7 in the form of metal electrotypes and the fixation of the stone mounts 1 in the metal powder 11 by the magnetization thereof enables in the ornament-making industry an economic manufacture of individual ornaments so that specified individual orders are feasible.

What is claimed is:

l. A process of manufacturing an ornament from a base, a

stone, and an pmamental element comprising horizontal pieces of wire oined to form a stone mount and vertical wires crossing and joined to said vertical wires and forming upstanding tips adapted to fix said stone and depending legs adapted to be joined to said base, which process comprises placing said stone mounts onto a die so that said legs extend upwardly, thermally bonding said legs to said base, and engaging said tips with a stone to fix the latter. 2. A process as set forth in claim 1, in which said legs are individually bonded to said base.

3. A process as set forth in claim 1, in which said legs are jointly bonded to said base.

4. A process as set forth in claim 1, in which a base is used which consists of an annular rail.

5. A process as set forth in claim 1, in which said legs are soldered to said base.

6. A process as set forth in claim 1, in which said legs are welded to said base.

7. A process as set forth in claim 1, which comprises embedding said stone mounts on said die in magnetizable metal powder in position on said die and magnetizing said magnetic powder to hold said mount in position while said legs are joined to said base. 8. A process as set forth in claim 7, in which said die is placed on an electromagnetic plate, said electromagnetic plate is energized to magnetize said metal powder, and said base is mounted in a holder, which is adjustable along a guide.
